A suicide attack killed five people at the interior ministry in Baghdad as a key political bloc called for early elections in a worsening standoff that has stoked sectarian tensions.
The blast, which left dozens wounded on Monday, came just days after the capital was struck by its deadliest violence in more than four months.
The parliamentary coailtion loyal to anti-US Shia cleric Moqtada al-Sadr said it backed the dissolution of parliament and early elections in a dispute that has seen Iraq's Sunni vice president accused of running a death squad and a deputy prime minister call the government a "dictatorship".
